It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides an end plate of novel laminate polymer battery module structure, as shown in fig. 1 to 3, include body 1, be located reserve coupling nut 2 on the body 1, set up in reserve fixed orifices 3 and the connecting piece 4 of cross-section for L shape on the body 1, body 1 includes outer frame portion 1a and is located connecting portion 1b in the middle of the outer frame portion 1a, x on the connecting portion 1b to having seted up the first connecting hole 5 of a plurality of, y to having seted up a plurality of second connecting hole 6, be provided with on the connecting piece 4 can with first connecting hole 5 or the fixed establishment that second connecting hole 6 is connected.
Fixing mechanism is including offering in the fixed orifices 7 of 4 one sides of connecting piece and can pass the dead lever 8 of fixed orifices 7, fixed orifices 7 is provided with a plurality of, a plurality of fixed orifices 7 can with first connecting hole 5 or second connecting hole 6 cooperatees, the cooperation is provided with fixation nut on the dead lever 8, the tip of dead lever 8 can with first connecting hole 5 or second connecting hole 6 screw-thread fit. The first connecting hole 5 and the second connecting hole 6 are all provided three, and the first connecting hole 5 located in the middle is overlapped with the second connecting hole 6 located at one end.
The connecting part 1b is provided with a plurality of mass reducing holes 9. The mass reducing holes 9 are located at the side portions of the connection lines of the plurality of first connection holes 5 and the connection lines of the plurality of second connection holes 6.
Two outer connecting holes 10 are formed in the other side of the connecting piece 4, and the straight line where the axes of the outer connecting holes 10 are located and the straight line where the axes of the fixing holes 7 are located are arranged in a staggered mode. The thickness of the connecting portion 1b is smaller than that of the outer frame portion 1a, and the connecting portion 1b is located in the middle of the outer frame portion 1 a.
When the battery module is normally installed, the novel end plate with the soft package battery module structure provided by the invention is used for firstly placing a rudiment battery module between two bodies 1, then respectively penetrating through reserved fixing holes 3 positioned at four corners of the bodies 1 at two sides by using four connecting screws, enabling the two bodies 1 to be close to each other by using the connecting screws and fixing the rudiment battery module, wherein the reserved connecting nuts 2 are used for connecting copper-aluminum bars of electric cores in series-parallel connection, namely the reserved connecting nuts 2 provide fixing points of the copper-aluminum bars of the electric cores in series-parallel connection. After the fixing of the rudiment battery module is completed, the connecting piece 4 is fixed to the first connecting hole 5 or the second connecting hole 6 through the fixing mechanism, and then the other side of the connecting piece 4 is fixed to the connecting rod welded on the inner wall of the battery box, so that the fixing of the battery module is completed.
Wherein, if the shape of the battery case is such that the battery module can be normally vertically mounted, the connection member 4 is connected to the first connection hole 5 in the x-direction at this time, if the depth of the battery case is shallow, however, it is necessary to horizontally mount the battery module, and at this time it is necessary to mount the coupling member 4 into the second coupling hole 6 in the y-direction, that is, the connecting piece 4 is also reversed in the horizontal direction, so that the connecting piece 4 can still be normally connected with the connecting rod, meanwhile, the horizontal two ends of the connecting rod can be welded with the inner wall of the battery box, so that the stability of the position and the shape of the connecting rod is guaranteed (the connecting rod positioned at the edge of the battery box can well keep the position, the position of the connecting rod positioned in the inner cavity of the battery box can also be well kept, and meanwhile, the position of a battery module positioned in the inner cavity of the battery box can also be well kept); since the installation process only needs to select the connecting member 4 and the first connecting hole 5 or the second connecting hole 6, the installation process is simpler.
When the connecting piece 4 is connected with the first connecting hole 5 or the second connecting hole 6, firstly, the connecting piece 4 is moved, three fixing holes 7 in the connecting piece 4 are respectively corresponding to the first connecting hole 5 or the second connecting hole 6, then the fixing rod 8 penetrates through the fixing holes 7 and is in threaded connection with the first connecting hole 5 or the second connecting hole 6, finally, a fixing nut is in threaded connection with the fixing rod 8, the fixing nut is rotated, and the connecting piece 4 is tightly pressed on the connecting portion 1b through the fixing nut, so that the connecting piece 4 is installed. Wherein one second connecting hole 6 at the end part is overlapped with one first connecting hole 5 in the middle, so the total number of the punched holes can be reduced, and the production cost and the difficulty are reduced.
The mass of body 1 has been alleviateed to the hole of subtracting matter 9, and a plurality of subtracts matter hole 9 and has made connecting portion 1b form latticedly, consequently still has sufficient structural strength, can normally support and fix electric core. Meanwhile, the deterioration hole 9 is located at a side portion of a line connecting the first connection hole 5 and the second connection hole 6, and thus, the connection portion 1b of the straight line where the first connection hole 5 and the second connection hole 6 are located has sufficient strength. Simultaneously outer hole 10 and fixed orifices 7 are the dislocation, are connected through the bolt between fixed orifices 7 and the connecting rod, consequently when rotating this bolt, can prevent to act on fixation nut, have improved the simple operation nature.
The thickness of connecting portion 1b is less than outer frame portion 1a thickness, and connecting portion 1b is located outer frame portion 1a intermediate position, and outer frame portion 1a has great structural strength this moment, guarantees that battery module has fine shape stability, and connecting portion 1b has reduced the quality of whole body 1 simultaneously.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
